Hi Elliott,

is never used anywhere, i noticed that there was a comment in the header of the
StochasticLoadBalancer but never mentioned anywhere else.
> Provide a way to throttle the number of regions moved by the balancer

> We have a very large cluster and we frequently add remove quite a few
> regionservers from our cluster. Whenever we do this the balancer moves
> thousands of regions at once. Instead we provide a configuration parameter:
> hbase.balancer.max.regions. This limits the number of regions that are
> balanced per iteration.
